`chainId` may be outdated if user changes chains as part of connection in @web3-react
### Impact
`chainId` may be outdated if the user changes chains as part of the connection flow. This means that the value of `chainId` returned by `useWeb3React()` may be incorrect. In an application, this means that any data derived from `chainId` could be incorrect.
For example, if a swapping application derives a wrapped token contract address from the `chainId` *and* a user has changed chains as part of their connection flow the application could cause the user to send funds to the incorrect address when wrapping. This is a common approach when using other foundational libraries like `ethers`
https://github.com/ethers-io/ethers.js, and most users of v8 will want to upgrade past the affected versions.
